@ sut this is a simple homemade press made by the user..using
thermal plastics for kydex no vacuum necessary..

I'm in no way promoting this material..or technique it is for
reference an learning purpose only about new materials an
thermal plastic forming
they have a cement to bond material seems

correct @sut.. for some things but not all polymers need a
vacuum.. they take shape on there own without a vacuum.. , a
seal a meal for vacuum converted just an idea for a vacuum
device?... an brace in your sagging weak spots... or make a
mold with a sold example..
just a suggestion...i just had a brace made for foot drop 6
months ago ...the mold was made like a cast/ sock stretched
..over my foot had a bag over foot first.... then cut away down
center with scissors before complete hardening/setup... an
this was like a sock material very elastic/sticky smoothed out
by hand ...an pliable.. but first i had to put a bag/ plastic
over my foot for removal... very sticky an they had gloves on...
then the pulled it over my foot like a sock.. before it harden
they cut it away with scissors.. .then the material was laid
in side an shaped.....
some guys are making there own spoilers on the back of there hot
fancy hot rod cars.. in there own garage a lot of good ideas
have come out of a garage!.. with some wood an fiber composite
materials.. there is a step by step by video on the net... i
watched them do the processes, turned out sweet.. an had the
shape of an airfoil? just an idea.. i under stand what lynx
said the average man dose not have access to the tools or time
to do such things but i say threw education an where there is a
will there is a way.... i move at a snail pace...wheels always
turning ..an I do think to much..that is what i got paid to do
....was to analyze improve an design.....we are not reinventing
the wheel just making it better an better..as we go..an some
times we get lucky an discovery mew things an new ideas to do it
easier.. along the way.. :) getting off topic simple is
best... i always believed that look at the car ...its not your
dads car any more but it is more efficient check out the solar
Prius video covered in solar cells asit was damaged in a hail
storm an he wanted to patch it..with solar cells an charge a
battery bank in his trunk an then powers his home when his care
sat in the parking lot all day while at work soaking up free
energy......... i have learned an was brought to my attention
more than once.. again its all about efficiency..in the circle
of life! how bout solar panels stuck to the air foils an
generating more power..that how my mind works...
happy

when i was young.. an bow hunted.. we would extend my arrows to
different sizes... with aluminum inserts using aluminum an
carbon fiber shafts.. but this will flex an not break different
function ..this is just to show as a fastener... nice tight an
strong fit ...for shaft alignment on (spars) hot glued or super
glue inserted fiberglass would be epoxy glued ... press fit in
fiberglass shaft end.. due it to both ends..... to extend a
shaft length or reconnect ...
then loctite with cut threads ..or do not loctite they make
two kinds of loctite.... to disassemble the spars for different
sizes or repair..where connected with a cut screw simple easy an
cheap! an threaded together on both ends ... you can counter
sink the rotar arm to attach to former ends top an bottom to
make for disassemble it was just a thought... in case a repair
was needed or something was interchangeable...
you could fasten from the top of former an the bottom an use to
reattach both sections? making one piece spar again ..with out
the option of gluing whole spar inside wing...i believe you
would not have to glue whole spar?..an still keep high strength
with inserts.they come in different lengths "carbon fiber is
great" but flexes until it is thicker in dia. when thin.in
size it is flexible under force you have aluminum shaft too....
should work well with fiberglass or all 3 though which ithink
fiberglass is cheaper but i have got good deal on all 3
materials.... an you can still seal to keep water out. jmho
another idea i had at 3 am? that woke me up!
not advertising just thinking outside the box...

@CG what material did you end up using..if you do not mind me
asking thx.. you have my email i am interested in many
composite an polymer an even resin lamination's ..the one good
thing with LYNX design in progress an i have thought seriously
about this is the material are mostly non conductive... i look
for this.. as characteristic so that i do not have a lighting
attraction object on a pole..an that lac of or electrical
resistance will not interfere with AC stator an rotor ...such as
a lighting strikes for static even bearing can play a roll..
sincerely

for @ness
i have been studying a similar vawt design ..on youtube... when
you say spikey explain please.. are you meaning not a solid
sine wave with current an omhs around 20... this design is made
with 9 coils made in a resin an 12 magnet on a saw blade for a
rotor excuse me for my novice ability to understand this, but
can a rectifier control this changing these problems going from
ac -dc back to ac..with some electronic device
question....why is everyone using wood an then sealing >? for
the top an bottom of vawt or center support...
for holding wing foil i have seen it called many different
things..... what is the correct terminology?....
rotor an stator one fixed to shaft an other to board top or
bottom of vawt or be it a center support with bearings i heard
something like a static bearing could cause a spike effect
maybe eddy currents? to halves one fixed one not,on the other
part an wing foil with wood an supports tied to air foil.. i
like the single center support design an pancake effect of PMA
an 3 air foils sleek design..... you need to slice threw the
wind cut like a knife.. an control voltage threw rpm many
variable.. while the air foil causes dynamic flow push /no
drag..pull... with least resistance for rpm ...i do not like the
shape or design of big bulky... looked good but heavy.. an to
many moving parts restricted air flow..i think i would change
the wood that hold the wing foils to a thin composite or
aluminum..or a thin concrete form plywood... an just seal..JMHO
there must be a logical reason. for your choice Lynx
no disrespect to ACE but this is his design did not produce
enough rpm not slender an sleek maybe bad wind location? i made
same mistake... i'm still learning in a learning curve... i now
single phase seems to be more efficient in 60hz but tell me
about spiky>? it could mean many things as i have researched the
subject matter a little an eddy currents ..burntit0017 had some
problems with this..i think i remember reading something
somwhere... could be wrong, i believe he knows about the subject
i'm no expert...on the matter of spiky or pma vawts

question on the 2 part sections of wing spars with caps for @
sut and lynx .. for joining both spars together at the rotor
arm.
( Lynx said in earlier thread: The spars are 1/2" OD
fiberglass rods. They are quite stiff. They have a 1/4"ID.
They will be cut to 24.375" and will join in the middle with a
1/4" OD spar and epoxy. Shipping 40" long rods caused shipping
rates to be high. The spars will fit diagonally in the box.
The bracing will be stainless steel and I don't have the
measurement yet.)
so if i understand there is a short piece of spar 1/4" o.d.
inserted into the 1/2 i.d." from spar to spar ? to make one
whole section again!.. inserted threw the rotor base arm pre
-assembled before the wings attached (the 1/4 i.d." is the pin?
to connect 1/2" spar halves?)... joins both sections of spars
together also epoxy on the wing caps to rotor arm base as extra
strength too ... making for a strong joining section all around
?.... there is no force or torque or stress at this mid because
of strength at this point of rotor blade arm an spars now ?
just curious of the forces here in mid section? as i think lynx
said torque on a pole!
i liked the two long one piece spars one full piece ? no
disrespect to redesign... this is strong design. JMHO
when in motion@high speed both ways
as i understand this to be true ..momentum forces torque pulls
outward... top an bottom an nothing but a slight belly egg
beater effect or slight helical twist , or nothing in the
middle threw proper force distributions of wing placement an
design such as with this build an experience.... no force
effect just torque at top an bottom ...it is all @ top an
bottom! thus requiring stainless steel brace strap @ top an
bottom? as middle section is now reinforced..
as @ness posted his rebuilt 75 video i wondered about this 2
part mid , spar section an investigated the torque placement
an force momentum on the spars an wings... his spars ..an I saw
he glued full length glued top to bottom of spar threw whole
wing...not sure how it was sheared or came apart.. it is
apparent there was an error of some sort as i may have missed
the details, some energy mass hit wing or torque , stress at
these points was in involved..am i missing something JMHO
i may be getting ahead an thinking to much..here. an over looked
some material posted already.
@ness your are right have adobean can do just as you say..thanks
need to figure out this old printer an find cables for printer
but i think i can do it at the library on thumb drive forthe
time being 10c a copie.

so this is is what i have researched an gathered as facts of
information..an as @sut said real testing will conquer.. with
your project lynx.

you can by longer section an cut to your requirements..or
applications..
this is a quick video that show's how we custom mfg. these take
down an reassemble sections.
the information an choice is yours to do as you please lynx..
i should design a take down insert fastener for market as i
have discovered they do not exist like this in various sizes for
this application an others.. or i did not look long enough i
have never seen any....? we just have always customized them

has anyone made the serpentine stator this is the difference in
performance from the one that has drag as you said Ness...
big difference an better result with speed with 3 blades..less
wire used to ....one continuous strand for each serpentine coil
3 phases..is there an advantage over individual coils? star or
delta
this was a great video as there are many!
i thought i may give this a whirl!

not sure where to put this as i was told to create my own forum?
when i asked the question ? it pertains to both the 75 an 175
new aluminum wing foil structure,i had a few questions of
concern.. for both .. parties..so here i go.. sticking to the
forum.
on the new wing design air foil i have a question.. for lynx an
member's
i believe you are making the wing foil from aluminum rolled
trim/flashing stock? ....i use this for many applications around
my house for siding as flashing, trim etc with my siding i use
a break for bending this material. there is a one time fold @
one edge of the alum trim sheet for tucking with an glued with
epoxy... Thickness of material (Nominal): 0.019"?
will there be dimensions for each sheet size layout to build our
own wing foil? DIY
or is this a purchase item in the kit from a vendor?......
i could figure this out with the former size... dimensions
JMHO.... i suppose.! again... is this a ..DIY build or a
kit item to purchase i have some material laying around... the
wing foil option is not clear etc..... or is this going to be an
item bought pre-assembled an we finish@ the final assembly
product.... with epoxy 3/4" ply former's top an bottom glued an
screwed to rotor arm an spars.. etc..
or are foil wings going to be sold as separate with former an
we just assembly..... i see your still in the design stage an
things are changing.....just a question? is this a separate
item/accessory in the kit should i make it.. DIY, or purchase
them?...such as with magnets ,spars ,coils. plate hub..etc,
with the kit..? just curious... about the tinsel strength of
this material ... this is hollow inside? i'm sure it will work
fine but.... these are 2 feet sections ..how will they hold up
in a storm? an torque stress high speed, i assume fine..with no
backing or filler material..?
after you make the first fold to tuck an epoxy along seam
....you have wing foil shape pretty easy DIY, is there going to
be a filler material in the foil wing for backing an support..
foam ect...?or a 3rd -3/4 former's in center.. one top middle
an bottom?
or a backing,liner Coroplast‎..some thin strength backing
inside or something to keep its shape an resist
denting..puncture etc. worst case scenario a storm an hail....
any applied rubber..?, just curious as what the tinsel strength
of the aluminum is under stress .0020.. if it where to take a
hit from a foreign object say a bird, hail branch flying
debris? etc i have all kind of things flying around in my yard
from storms,neighbors, traffic etc......... i use this material
all over an have seen what happens to it under worse case
conditions? ...for my trim on my house an small projects i use a
backing... but it what it is.. has a backing an still dents on
my house....... not criticizing or objecting to the wing foil
it is @lynx / @sut wing foil design great idea an economical
easy to way build.... its great! easy an fast to build
inexpensive DIY.... just an observation from use.
my question is will it be hollow inside without support backing
inside just spars threw wing-foil glued with epoxy to former's
an spars screwed into rotor arm base..an take weather abuse /
bird hail branch flying debris..etc.an stress endured an keep
its shape.. just an honest question an thinking aloud to much i
guess. we will have to see with real test conditions an stress
analysis. gentlemen good day.. i had to change out my flag as it
was ragged an torn but that's just nylon blowing in the wind.
happy.
